And where would we jump to if there's no information on the location?

I've checked some log files of mine, and I didn't find a singular
version ("at line X").  But if you have them, the surely are possible.
One strange thing I found in my logs is that the first line may be
larger than the second, i.e.,

  Overfull \hbox (1.95412pt too wide) in paragraph at lines 8--1

But those seemt to appear only in pygtex files, i.e., code listings
texified by pygments using the minted LaTeX style.

I'd start with the stricter version for now, i.e., the first version
with additional trailing $.
